Juraj B. - Fellow Monerites, are we lost? (MoneroKon 2025)

Remember when Linux users went for “like Windows, but cheaper?”. They’ve lost their edge - libre, better, customizable, loved by users, stable and performant. Are we Monero folks just “Bitcoin with better privacy,” clinging to a fading dream? Network effects are kicking our ass—money loves a crowd. Is there still some place for us in the world? Are we the last cypherpunks or are we doomed to be the crypto equivalent of groupies for a band that’s already broken up? I’ll propose some meaningful things we can do in this situation.

afungible - Unleashing the Flood: Stress-Testing the Monero Network (MoneroKon 2025)

On 2022-08-12, the Monero network was stress-tested with ~50,000 transactions and under $1,000 in fees in 24 hours, triggering “dynamic block sizing” for the first time, and highlighting performance constraints. Under peak load, a few nodes crashed, and the average confirmation times rose from about 2 minutes to roughly 30 minutes (≈ 15 blocks). Services like CakeWallet, by then running on “default low-priority fees”, also experienced a multihour slowdown, with some users reporting waiting times of 3 hours (x.com/cakewallet/status/1558094085642194945). These results expose concrete performance constraints in fee estimation, mining rules and node stability, and point to targeted improvements for optimized transaction pool management and adaptive fee algorithms to bolster the resilience of Monero. The findings underscore the need for ongoing, high-intensity testing, to ensure Monero can more efficiently handle unexpected traffic spikes without sacrificing privacy or decentralization.

Jeremy Rand - SocksTrace: A Proxy Leak Detector for Anonymity-Focused Network Applications (MoneroKon)

Monero has excellent transaction-level privacy, and things should get even better soon with FCMP++s. But these innovations aren’t sufficient if you have deanonymization vectors on the network level. Tor gives you network privacy in theory — but how do you know your Monero wallet isn’t leaking some network traffic outside of Tor? Proxy leaks are a surprisingly common class of security vulnerability, and they’ve historically been difficult to audit for.

Joseph The Parrot - Beyond the FGC9: Shaping the Next Steps of True Liberty (MoneroKon 2025)

1.The basics of the legal circumstances both inside and outside the USA. 2.The New Second Amendment: Self defense is a universal human right, regardless of nationality. 3.The three design objectives of The New Second Amendment and the triple constraint they form. 4.The FGC-9 was the first attempt at overcoming the triple constraint. 5.How the Urutau refines the FGC-9 concept, being cheaper, easier to make, more reliable, and more OpSec-aware.

Yu - Eclipse attacks on Monero peer-to-peer network (MoneroKon 2025)

Yu - Eclipse attacks on Monero peer-to-peer network (MoneroKon 2025)

While the decentralised nature of Distributed Ledger Technology systems suggests the absence of a central authority, it does not eliminate the possibility of supernodes within the network. To investigate this, we collected peerlist data from TCP flows, validated our connection inference algorithm, and mapped the Monero network’s structure, achieving high accuracy that improves with longer observation periods. This study is the first to uncover connectivity patterns in Monero’s updated peer protocol, providing visual and structural insights into its topology. A key focus is an interconnectivity among the 14 highest-degree nodes and their immediate neighbours. With a reasonably accurate approximation of the network structure, simulating an Eclipse attack becomes feasible. Furthermore, overlapping neighbours among supernodes enable attackers to reduce the number of unique connections required, making such attacks more cost-effective.

Marcel Plch - We allowed cyberpunk dystopia without the good stuff (MoneroKon 2025)

Money is now primarily digital, under full control of the governments or respective organs, corporations hoard wealth like never before, FIAT money, which is what most people have, loses drastically on value due to inflation. Yet, there is no cool cyberware, no Shinkanzen trains in almost all cities, and the best we got in AI are overbloated chatbots. Now what?

deki - How Ayn Rand’s Ideas Connect to Privacy and Crypto (MoneroKon 2025)
S2025:E21

deki - How Ayn Rand’s Ideas Connect to Privacy and Crypto (MoneroKon 2025)

This presentation explores the intersection of Ayn Rand’s philosophical principles, particularly her emphasis on individualism and personal sovereignty, with the concept of privacy in the context of cryptocurrency. Rand championed the right of individuals to control their own lives, property, and decisions, free from external force. I’ll be discussing how cryptocurrency—decentralized, pseudonymous, and resistant to centralized oversight—embodies Rand’s ideals by empowering individuals to safeguard their financial privacy against the surveillance state and institutional overreach. Crypto feels like a real-world spin on Rand’s vision, giving us a way to take back control. Ultimately, my goal is to show how Rand’s philosophy provides a compelling intellectual foundation for understanding and advocating privacy in our modern era.

S2025:E22

Francisco "ArticMine" Cabanas - The FCMP++ Monero Fee Market – Post-Emission Fee Market Implications (MoneroKon 2025)

Monero uses an adaptive block weight based upon the CryptoNote excess size penalty with a short term median over the last 100 blocks, bytecoin.org/old/whitepaper.pdf This leads to the Monero fee market. We will consider the impact of FCMP++ on this fee market. In the particular necessary changes to support FCMP++, the impact FCMP++ on spam attacks, and the critical importance of the tail emission on proof of work security, growth management and spam control. We will also discuss the resulting transaction fee changes and simplification of the transaction fee calculations by Monero wallets. We will also consider the implication of The FCMP++ Monero Fee Market on both small block (Bitcoin Core type) and large / adaptive block (Bitcoin Cash type) post emission fee markets.

Robert Blinov - The Value of P2P Networks (MoneroKon 2025)
S2025:E23

Robert Blinov - The Value of P2P Networks (MoneroKon 2025)

In my talk, I will describe the advantages (and pitfalls) of P2P networks, including how they can help bypass censorship, as well as needless centralisation like ICANN’s domain-name monopoly. I will explain the value of mesh networks and their great untapped potential — how they can be used to save lives during emergencies and make digital communication more efficient. I will give examples of mesh networks used today, such as Meshtastic, and will warn about the perverse, surveillance-focussed use of mesh networks by companies like Apple and Google.

Martin Arness - Monero After DAC8: Building Anonymous Off-Ramps (MoneroKon 2025)
S2025:E13

Martin Arness - Monero After DAC8: Building Anonymous Off-Ramps (MoneroKon 2025)

The EU’s DAC8 directive, alongside MiCA and CARF, is the next phase of global financial surveillance - mandating centralized exchanges to report user holdings and transactions straight to tax authorities. This talk explores what that means for the future of privacy-preserving cryptocurrencies like Monero. While XMR is resilient on-chain, the off-ramp problem remains unsolved - especially for large-value exits. Without a sustainable, anonymous OTC ecosystem, Monero’s true potential remains bottlenecked. This presentation will break down the coming regulatory wave and open the floor to building the next generation of off-ramping infrastructure.

Alan Szepieniec - Post-Quantum Anonymous Transactions without Signatures (MoneroKon 2025)

Nearly all blockchains in existence use digital signature schemes for unlocking funds for expenditure, even though this primitive is overkill for that purpose. A commitment scheme suffices, as long as the opening protocol binds to the transaction. Moreover, and perhaps surprisingly, this minimally sufficient primitive can be compatible with an architecture for anonymous payments – and, incidentally, post-quantum security.

Harry Halpin - How NymVPN works: A decentralized privacy-first VPN and mixnet (MoneroKon 2025)
S2025:E11

Harry Halpin - How NymVPN works: A decentralized privacy-first VPN and mixnet (MoneroKon 2025)

Nym is a noise-generating mixnet built on top of a decentralized network. By adding noise and mixing packets in its anonymous overlay network with per-packet routing, it accomplishes superior privacy to existing VPNs and even Tor. It also offers a “fast” mode that turns mixing off and offers speed comparable to VPNs, and is faster than Tor. NymVPN is an interface, for all major operating systems, that makes using the Nym mixnet as easy as using a traditional VPN. No identity is required to subscribe to NymVPN as users are identified with key-pairs where the keys are used to create unlinkable anonymous credentials. These anonymous credentials are then used to “log in” to the VPN and delink any payment from usage of NymVPN. And Monero can be used for payment!

Aaron Feickert - Mnemonic seeds for risky situations (MoneroKon 2025)
S2025:E10

Aaron Feickert - Mnemonic seeds for risky situations (MoneroKon 2025)

An important but overlooked use case for digital asset mnemonic seeds is risky situations like border crossings, where inspection or seizure of property could make possession of a written mnemonic dangerous. How can these situations be handled safely? We will look at existing approaches with a critical eye and identify important concerns. We will then propose a controversial alternative that uses off-the-shelf cryptographic components in a new way.

hbs - Reviving EVM-based Monero Atomic Swaps (MoneroKon 2025)
S2025:E09

hbs - Reviving EVM-based Monero Atomic Swaps (MoneroKon 2025)

As Monero continues to be regularly delisted from centralized exchanges, P2P services, and decentralized exchanges, atomic swaps are bound to attract increased liquidity. While BTC-XMR atomic swaps have made a lot of progress, Ethereum-based ones have stalled after their initial momentum. This talk will go over some changes which could be introduced to make atomic swaps easier to use and more popular on EVM-based blockchains, from a technical standpoint as well as from a user’s one.

CJ & Sean Coughlin - Grease: a mimimal payment channel implementation for Monero (Monerokon 2025)

CJ & Sean Coughlin - Grease: a mimimal payment channel implementation for Monero (Monerokon 2025)

Off-chain payment channels have tremendous utility. Thousands of transactions can be aggregated every minute without consuming block space; and seamless point-of-sale transactions would make Monero purchases feel no different to using a credit card or Venmo. Unfortunately, payment channels require a persistent state mechanism to keep track of the payment channel balance; something that is highly unlikely to be introduced to Monero (for good reason). Therefore it may appear that payment channels are impossible in Monero. Enter Grease: a minimal, bidirectional proof-of-concept payment channel implementation for Monero. It makes use of verifiable, consecutive, one-way functions (VCOF) and consecutive linkable ring adapter signatures (CLRAS) in concert with a smart-contract enabled blockchain (SCEB) to provide payment channels with the promise of unlocking these and other use cases.

jeffro256 - Planned and speculative block changes in Monero (MoneroKon 2025)
S2025:E07

jeffro256 - Planned and speculative block changes in Monero (MoneroKon 2025)

There are a few planned changes to Monero’s consensus protocol revolving around the block format. A tweak to the PoW algorithm, RandomX, would allow for stability against DoS attacks with significant improvements to negative testing speed in the average case. On the FCMP++ side, to allow for wallets to check FCMP trees provided by nodes, a field called the “FCMP tree root” will be added to the block data. I will also discuss a more speculative change to the p2p protocol which would allow for header-only sync in Monero, and what has already been done to get that set in motion. The combination of all these changes have strong implications for node stability, wallet trust requirements for remote nodes, and the possibility for efficient SPV wallets. About the Speaker: jeffro256 has been contributing to the Monero core repository for over two years with 98 merged commits to master thus far, and many open PRs. He is the lead developer of Carrot (Cryptonote Address on Rerandomizable-RingCT-Output Transactions), which might become the main supported addressing protocol post-FCMP++. He also worked on the Seraphis migration project in 2023/2024. carrot

Aaron Feickert - Rings and trees: how to prove coin ownership (MoneroKon 2025)
S2025:E06

Aaron Feickert - Rings and trees: how to prove coin ownership (MoneroKon 2025)

The current Monero protocol uses linkable ring signatures to prove coin ownership in a way that doesn’t leak the specific coin. But other designs do things differently! In this talk, we’ll look at different approaches to proving ownership in digital asset protocols: Monero (today and tomorrow!), Firo, and Zcash. Each offers a unique and interesting look at how we can use different cryptographic techniques toward the same goal. About the Speaker: Aaron Feickert is a cryptographer, mathematician, and physicist whose current research focuses on privacy-preserving signature and proof constructions.

Anhdres - Hooks & Loops (MoneroKon 2025)
S2025:E05

Anhdres - Hooks & Loops (MoneroKon 2025)

This talk begins with a dissection of life’s winding paths, exploring the choices and paths that brought each of us to MoneroKon. We’ll look at how well-known members of the Monero community first discovered Monero, pinpointing the specific moments or details that made it stick to them. Then we’ll explore nature’s design: the hooks and loops that help burrs spread their seeds far and wide, and how that mirrors human attitudes. Some of us are mostly hooks, creating tiny signals and events that invite others in. Others are mostly loops, passive consumers of media and tools. I’ll focus on practical strategies to increase the hook ratio. Because Monero needs more Velcro: more connections, people staying around, and maybe a bit more noise. Life’s too short to walk around with just loops hanging out. About the Speaker: Visual artist based in Buenos Aires, with a background in storytelling, animation, and design, anhdres specializes in educational content, trying to bridge the technical and the emotional (when he succeeds). A Monero believer since 2017, he is the non-coding half of the Monerujo team. He creates visuals for Cypher Stack and co-hosts weekly Spaces for Cake Wallet. Conflict of interests is his middle name. He’s the author of the Monero Garden project and the illustrator of “Mastering Monero”. He hosts Café Monero and previously co-hosted the Spanish-language podcast El Monero. He has spoken at Monerokon, Monerotopia, Labitconf, and the Greyhat Conference. Basically, he happily and clumsily jumps on stage to speak about things he cares about, in the hope it’ll do some good.

Rucknium - OSPEAD: Optimal Ring Signatures (MoneroKon 2025)

OSPEAD estimates the age distribution of the real spend in Monero’s ring signatures. Monero’s decoy selection algorithm could be changed to closely mimic the real spend age distribution, yet an anti-privacy adversary can also use the real spend distribution to execute the MAP Decoder attack on past ring signature data. The attack raises the probability of correctly guessing the real spend in a 16-member ring from 6.25% to 23.5%, on average. Multiple nonstandard decoy distributions are modeled as repeated measurements drawn from unknown distributions components, then estimated by the method of Bonhomme, Jochmans, & Robin (2016). The age distribution of ring signatures associated with a given decoy distribution is modeled as a two-component mixture distribution. The decoy distribution is subtracted from the on-chain data distribution to obtain the real spend distribution.

Rucknium, Boog900, xenu - Defeating Spy Nodes on the Monero Network (MoneroKon 2025)
S2025:E02

Rucknium, Boog900, xenu - Defeating Spy Nodes on the Monero Network (MoneroKon 2025)

According to recent analysis by the Monero Research Lab, one or more anti-privacy adversaries have set up many spy nodes on the Monero network, composing up to 40 percent of reachable node addresses. Connections to these spy nodes would make up an estimated 15 percent of the privacy-sensitive outbound connections established by honest nodes that use the default configuration. This talk will quantitatively estimate the privacy impact of spy nodes even when Monero’s Dandelion++ protocol is used. The following countermeasures will be evaluated: opt-in IP address ban lists, anonymity networks like Tor and I2P, a Dandelion++ alternative called Clover, subnet de-duplication, and protocols that verify that an internet address is really operating a distinct node. The Confidentiality, Integrity, and Availability triad in information security will guide comparisons of these countermeasures.
